Great product. I love Alchemy shadows. The quality is amazing! So smooth! Think MAC Veluxe but smoother plus shimmer. Blue flag is bright blue shadow. Similar to MAC Electro sky and blue shade from NARS Rated R duo. Actually I was looking to buy that NARS duo, but they were out, so I picked Blue Flag. I am so glad I did. Its so much better in quality! I use it as a liner or all over lower lid for a really bold look. If you love bright shadows and can pull off blue like I can, this is a must! The pot is hard to open however.
from the reviews of the blue in the nars rated r duo, blue flag sounds a lot like it. ive seen tthe duo at sephora before, but never really paid much attention to it. i think the blue in the duo is a tad bit brighter, but nevertheless, this is a very attention-catching intense cornflower blue. it also has lots of fine turqoise-aqua shimmer to it, but it doesnt show much on your eyes unless you really pack the eyeshadow on. i dont really wear this much in public anyways mainly becuase i dont really know how to wear it. but i think this is a rather retro and funky shade, just not for those who dont like bold e/s. i wont have bought this from the looks of it, (it was a gift thanks amber!), but its still a keeper and i enjoy having this. i wish there was a mirror with this, though!!!
